Abstract

On décrit des compositions de copolymère d'éthylène utiles pour la fabrication de feuils ou d'articles moulés. Ces compositions contiennent des composés qui réagissent en présence du copolymère pour libérer un gaz formant des bulles dans les feuils du produit terminal ou les articles moulés. Ces bulles confèrent des caractéristiques esthétiques souhaitable aux produits terminaux.
